About Capital Electro Circuits Inc

Capital Electro Circuits Inc., based in Gaithersburg, Maryland, has been fabricating printed circuit boards since 1985. The company operates as a domestic manufacturer of rigid, flexible, and rigid‑flex PCBs, with a focus on specialty designs that fall outside standard fabrication lines. The shop produces multilayer boards up to 16 layers, with finished thicknesses up to 1.300 inches, and offers advanced features such as blind/buried vias, edge plating, castellations, and controlled‑impedance structures. It works with a wide range of high‑frequency and high‑reliability laminates — including Rogers, Taconic, Arlon, and TMM series — and provides a full suite of surface finishes (HASL, ENIG, ENEPIG, hard gold, immersion tin/silver). In‑house capabilities cover CAM/DFM, drilling, plating, etching, LPI soldermask, legend printing, CNC routing and scoring, and electrical test (continuity/isolation up to 250 VDC). The company serves aerospace and defense (including programs for Northrop Grumman, BAE Systems, NASA, Lockheed Martin, Honeywell, Sandia National Laboratories, Booz Allen Hamilton, and the U.S. Army), medical imaging and diagnostics, telecommunications (5G and satellite), automotive and electric‑vehicle systems, and RF/microwave applications up to 100 GHz. It emphasizes 100 % U.S.‑based production for military and avionics work. Capital Electro Circuits differentiates itself by taking on “specialty” jobs that lack defined manufacturing methods, developing custom processes to deliver working parts on short notice. It maintains ISO 9001:2015 certification, UL recognition, RoHS compliance, ITAR registration, and a conflict‑minerals sourcing policy, and offers blanket orders with split deliveries.
